ARTÍCULO Effect of Scrap Quality on Coreless Induction Melting Time and Efficiency
By Rod Naro, Peter Satre, and D.C. Williams
One of the significant economic forces driving foundry operations today is the necessity to reduce melting costs and improve operating efficiency. Often, these two approaches do not yield the same result. For example, purchasing relatively inexpensive scrap metal units can reduce raw material costs overall, but at the same time can have a significant and deleterious effect on furnace efficiency.
In the past 60 years, the melting of various ferrous charge metals in coreless induction furnaces has changed. As the quality of the metallic charge constituents steadily deteriorated, slag-related melting problems such as slag build-up became widespread. Slower melting rates and less efficient use of the coreless induction furnace result.

ARTÍCULO Global Impact of Redux Fluxes to Reduce Slag Build-Up
By Rod Naro and D.C. Williams
Newly engineerred fluxes can extend refractory life in coreless induction furnaces, prolong service life of pouring ladles, and significantly reduce slag and/or dross.
During the past 40 years, the melting methods andassociated molten metal-handling systems used by U.S.foundries have changed significantly. Further, the qualityof metallic scrap and other iron-unit feed stocks hassteadily deteriorated. The result: Increased slag generationand slag related melting problems have becomewidespread issues in recent years. A search of the foundrytechnical literature about slag control and build-up from the past 40 years finds only a handful of articles.

Case Study #1 Internal Foundry A: REDUX EF40L Flux TRIAL
OBJECTIVE
Clean slag buildup from coreless induction furnace walls
TEST CONDITIONS
- Metal Grade - Grey Iron
- Item Name - Differential Housing & 3 Cylinder Engine Block
- Furnace Capacity - 7 Metric Tons
- Furnace Number - 1
- Heat No - 308
Trials were conducted at the furnace:
- Redux addition level - 0.05% of metal based on treated metal weight, i.e. 3.5 kg per heat of 7 metric tons.
- Half of the 3.5 kg of Redux was added with 50% of the charge, and the balance after melting started.
RESULTS & CONCLUSIONS
The furnace was mostly clean and free from buildup after just one Redux EF40L addition; a second and third addition of Redux appeared to remove all slag buildup.
Foundry A was very satisfied with the performance of Redux EF40L!
